Turning Torso Skyscraper in Malmö, Sweden - Discovery Channel (2004) - Extreme Engineering 1/4

Turning Torso Skyscraper in Malmö, Sweden - Discovery Channel (2004) - Extreme Engineering 1/4 HSB Turning Torso is a skyscraper in Malmö, Sweden, located on the Swedish side of the Öresund strait. It was designed by the Spanish architect Santiago Calatrava and officially opened on 27 August 2005. The tower reaches a height of 190 metres (623 feet) with 54 stories. Upon completion, it was the tallest building in Scandinavia, the tallest residential building in the EU and the second tallest residential building in Europe, after the 264-metre (866 ft) high Triumph-Palace in Moscow. A similar, taller skyscraper featuring a 90° twist is the Infinity Tower, currently under construction in Dubai, United Arab Emirates. Prior to the construction of Turning Torso, the 86-metre (282 ft) high Kronprinsen had been the city's tallest building. The tower's design is based on a sculpture by Calatrava called Twisting Torso, which is a white marble piece based on the form of a twisting human being. The organizers of the European housing exhibition Bo01 held in Malmö in 2001 asked Calatrava to design a temporary pavilion for the exhibition. At the same time a high-rise building was proposed for the exhibition site and discussions started with Calatrava about the design of that. Construction started in the summer of 2001. One reason for the building of Turning Torso was to re-establish a recognizable skyline for Malmö since the removal of the Kockums Crane in 2002, which was located less ...

ROLL KRAFT F-10 PANEL PRE CUT CHANNEL

This new thru-spindle model was built especially for the profile that has a variety of overall widths, such as drywall studs, door panels, etc. This new model has three outstanding features over previous panel mills. First, with the use of solid telescoping spindles and fully supported heavy outboard housing, you can obtain an enormous strength advantage over conventional, unsupported, overhung stub-type machines. Second, width changes can be obtained simply by a turn of a crank or the push of a button. This can reduce tooling changeover time to minutes. (The Series F Panel Mill can be made with one or both sides adjustable.) The third feature is lower cost. Since the new model has only one bank of drive housings versus the two banks required for the old design panel mill, the new model is much less expensive. Ardcor is the "run source" for one-source buying of roll forming equipment. Specifications: ARDCOR self-contained drive stands with individual oil supply permit quick removal and rearrangement of units without having to drain oil from all units. Double bearing support on both top and bottom spindles of drive unit gives added rigidity and lasting alignment. Individual worm shaft drive features chain type couplings for linking units together. Worm gears are made of high quality gear bronze for longer life. Gearing arrangement keeps gear train in mesh through complete range of vertical shaft adjustment for different roll diameters. Roll spindles and worm shafts are ...
